Radio static elimination

My invention relates to improvements in radio static elimination. It relates particu larly to radio wave receiving conductors and processes of treating same.

a One of the objects of my invention is to provide a novel radio wave receiving conductor, such as an aerial, lead in wire and conducting wires of a radio receiving set, which conductor will reduce the static disturbances in the set, as compared with similar conductors which have not been treated similarly.

A further object of my invention is the provision of a novel process for treating radio wave receiving conductors, by which they acquire the characteristic of reducing static disturbances in the sets in which they are used.

The novel features of my invention are hereinafter fully described and claimed.

My improved process consists in heating to a red heat and cooling by contact with an oleoresinous material, such as turpentine or resin in solid or liquid form, and, preferably, by immersion in the oleoresinous liquid, a wave receiving conductor of a radio receiving set, such as an aerial, lead in wire, or other conductors through which pass the radio waves.

The conductors to be treated, as has been described, are those comprising metals, such as copper, brass, bronze, phosphorous bronze or others which are electrically conductive, and which, when so treated, and employed in a radio receiving set, will reduce the static I disturbances in the set.

' In practising my process, the conductor to be treated, such as copper wire or copper ribbon, is heated to a red heat, above the boiling point of the oleoresinous material, and then cooling the conductor, preferably by immer- 40 sion, in the turpentine, liquid oleoresinous material, such as melted resin.

Conductors so treated, which have the characteristic of reducing the static in a radio receiving set, may be the aerial, lead in conductor, tuning coil, ground conductor or other conductors in the set which receive the radio waves, or all of them.

I have found by test that radio receiving sets which have been noisy with static disturbances at a given time, have these dis- Application filed February 23,1929. Serial na aaasiz.

turbances entirelyeliminated, so far as hearing'them is concerned, or greatly reduced in volume, after an aerial, which has been subjected to treatment with my improved process, has been substituted for the one which had just been used, and that the disturbances immediately recurred upon the replacement of the first aerial.

Modifications of my invention, within the scope of the appended claims, may be made without departing from the spirit of my invention.

What I claim is 1. In radio static elimination, the process consisting in'heating to a red heat and cooling by contact with oleoresinous material, an electrical conductor, which, when so treated, has the characteristic of reducing static disturbances in a radio receiving set, when used therein as'a radio wave receiving element. 7
